Not an attorney
It does NOT mean you are exempt from the 1 year separation requirement. You are still required to wait a year. Also, NC is a no-fault divorce state.
It means that you can pursue a torte claim (law suit) against the paramour. However, if you do some research on it you will find the claims are VERY expensive to pursue (tens of thousands of dollars) with an unlikely chance of recuperating those expenses unless the paramour is quite wealthy. Most regular individuals can find exemptions to paying the judgement (judgement proof).
Your best bet is to leverage it during negotiations while keeping in mind what I’ve written above.
